How the Test Works
The test uses a specialized probe to detect genetic material (nucleic acid) from the coronavirus. A swab is collected from your upper respiratory tract (like your nose or throat), and the sample is analyzed in a lab to identify the virus’s presence.
Sample Collection
You’ll likely have a quick, painless swab of your nose or throat. The sample is then sent to a lab for testing. No special preparation is needed, but avoid eating, drinking, or smoking for about 15 minutes before the test.
What to Expect After the Test
Results are typically available within 24 to 48 hours. If the test is positive, it means the virus may be active in your body. If negative, it suggests you are unlikely to be infected at the time of testing.
When This Test Is Used
Doctors use this test to diagnose suspected COVID-19 infections, especially in people with symptoms like fever, cough, or shortness of breath. It may also be used in screening or monitoring for exposure in high-risk settings.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive result strongly suggests active infection and may guide treatment decisions, such as isolating at home or seeking further medical care. A negative result does not definitively rule out infection, especially if symptoms persist or you’ve been exposed recently. This test is most reliable when performed early in the illness.
